Daily Light Integral Calculator

Put simply dli is a measurement of how much usable light hits a certain area one square meter to be exact per day.

Daily light integral calculator.

Enter only two of the three pieces of information in this app to calculate the third unknown value. It is a very useful metric to determine if a particular location receives sufficient amounts of light for plants to grow well. Introducing agritecture s dli calculator a digital tool allowing users to estimate the daily light integral dli in any location on earth. For example enter light intensity.

Interactive graphs plots help visualize and better understand the functions. It is expressed in terms of moles of light per square meter per day or mol m 2 d 1. The integral calculator supports definite and indefinite integrals antiderivatives as well as integrating functions with many variables. For more about how to use the integral calculator go to help or take a look at the examples.

This metric is important to measure since the amount of light your plants get in a day. It is a function of photosynthetic light intensity and duration day length and is usually expressed as moles of light mol photons per square meter m 2 per day d 1 or. It is the measurement of the total amount of light that falls in a certain location. Dli stands for daily light integral.

Mol m 2 d 1. Daily light integral or dli are the total amount of photons in the par 400 700 nm range that land on a target point over the course of a day meeting proper dli requirements has a big impact on a plant s root and flower development. Daily light integral dli dli ppfd over the course of a light cycle measured as moles of par photons per day example. You can also check your answers.

Calculate the light intensity and photoperiod required to achieve a certain daily light integral for an electric light source such as indoor led light emitting diode lighting. The daily light integral dli is the number of photosynthetically active photons photons in the par range accumulated in a square meter over the course of a day. Daily light integral calculator. Different types of plants require different dli levels and have different photoperiods so check out some excellent research on the subject done by the purdue.

One of the go to lighting metrics of greenhouses is dli or daily light integral and you may see this acronym when you re trying to figure out how much light a specific type of plant needs. Daily light integral referred to as dli is the amount of photosynthetically active radiation par received each day as a function of light intensity and duration. Knowing the dli is important in determining if there is sufficient natural light for your crops or if supplemental light is required for your greenhouse operation.
